Brandon Schneider	436e5ae8ca	feat(pist): flexure features v2 — full spectral profile per joint ... - Each flexure now stores: spectral_gap, adjacency_eigenvalue_max/min, laplacian_eigenvalue_max/min, laplacian_zero_count, singular_value_max, matrix_size, rank, density, trace, frobenius_norm - feature_version: 'flexure-spectrum-v2' in decision_signals - v1 classifier results preserved (52.6% tactic, 50.0% joint, 84.2% RRCShape) - Spectral features enable richer distance computation as dataset grows - Old flexures cleared and re-ingested with full spectra - Session: ae31d595-0535-4a0c-9d41-af9c0357dba1	2026-05-26 11:00:31 -05:00
Brandon Schneider	0f15842507	feat(pist): joint-based classifier — 84.2% RRCShape from flexure motifs ... - Joint library classification: nearest-motif from ene.flexures - Leave-one-flexure-out evaluation on 38 joints - RRCShape: 84.2% (baseline 60.5%) — ★ highest accuracy seen - Domain: 76.3% (baseline 60.5%) - Tactic family: 52.6% (baseline 31.6%) - Joint label: 50.0% (baseline 13.2%, 3.8× baseline) - Simple 5-dim feature vector + nearest-neighbor - Story: new proof traces can find similar stored joints and get predictions	2026-05-26 10:56:01 -05:00
